关于均相成核与异相成核对结晶度的影响以及这种影响对结晶温度和熔点有什么影响?This accelerating influence of the reinforcing fibers is related to the faster heterogeneous nucleation occuring in the filled polymer vs. homogeneous nucleation in the unfilled grade。The effect is therefore more pronounced at high temperatures of crystallization approaching the melting point。这句话怎么理解?怎么就异相成核速度快,表明在高温下结晶接近熔点,完全不通啊!!!!!!!!!有没有朋友能帮我解决一下对这句话的理解。查看更多7个回答 . 7人已关注
关于IR降是怎么产生的,跟离子扩散受阻有关系吗?求助各位大侠,小女子有事相求,电压降产生是因为离子扩散受阻吗?还是这是没有关系的,是由于内阻所致?因为审稿人让我给出证据,我说“at high current densities, the potential drop is visible due the limitation of ionic diffusion." 审稿人问:What is the evidence?查看更多7个回答 . 23人已关注
